General Notes:

1. Merrimac Phase Comparators provide two output

signals each of which is proportional to the phase

relation of the two inputs.

2. One output is proportional to the sine of the

relative phase angle between the RF and LO inputs

while the other output represents the cosine of the

relative phase angle between the inputs. Using the

sine and cosine outputs together resolves the

inherent

for both outputs.

3. The phase comparator is an integrated assembly

consisting of a power divider, two balanced mixers

and a 90° quadrature hybrid. Two diplexers

attenuate the second harmonic (2 f

4. Custom designs are available that provide higher

precision and better accuracy. Inquiries concerning

your special applications are welcomed.
